Collecting Materials for a Homemade Solar Cell

Starting your homemade solar cell project will need a few key materials. Titanium dioxide (TiO2) is the main one. You can get this from powdered donuts. You’ll also need conductive glass slides, ethanol, a hotplate, and berry dyes.

Powdered Donuts as a Source of Titanium Dioxide

Titanium dioxide is vital for your solar cell. It helps turn light into electricity. You can get TiO2 from powdered donuts without spending much money. This makes the project simple for anyone interested in green energy or studying STEM.

Conductive Glass for Solar Cell Construction

Your solar cell’s electrodes will be made from conductive glass. It’s got a layer of indium tin oxide (ITO) or fluoride-doped tin oxide (FTO). These glass panels are good at moving electric charges. So, your solar cell will work well, making a bit of power from light.

Additional Supplies Needed

Besides what was mentioned, you’ll also need ethanol, a hotplate, a graphite pencil, an iodine electrolyte, and berry dyes. These help in making the titanium dioxide solution, coating the conductive glass, and putting together the solar cell. It’s a fun and learning-filled way to experiment with renewable energy.

With just a few items from home, you can start a solar cell project. Fenice Energy loves to back clean energy initiatives like this. It encourages more people to try sustainable energy and help the planet.

Extracting Titanium Dioxide from Powdered Donuts

To make homemade photovoltaic cells, we must first get titanium dioxide (TiO2). We can find this vital material in a surprising place: powdered donuts. This common and inexpensive item is perfect for the key semiconducting layer in your solar cell project.

Dissolving and Filtering the Sugar

Begin by mixing powdered donuts with warm water. Stir until the sugar fully dissolves. This creates a sweet liquid you can then filter. This step separates solid particles, leaving a mix rich in TiO2.

Removing Fats through Baking

Next, bake the filtered mix at a high temperature, about 500°F (260°C). This high heat removes any fats or oils. What’s left is pure titanium dioxide powder. It’s now perfect for making solar cells. This careful method ensures your solar project uses the best, purest materials.

Preparing the Titanium Dioxide Solution

The first step to make a solar cell is to prepare a titanium dioxide (TiO2) solution. This solution will coat a glass slide, making it the solar cell’s photoanode. We mix the TiO2 from powdered donuts with ethanol to get a thin, even coating on the glass.

Ethanol is key for making the TiO2 stick well to the glass. It ensures the TiO2 spreads out evenly. This even coating is super important for the solar cell to turn sunlight into electricity well. By doing this step right, you’re on your way to a great homemade solar cell.

For your project, Fenice Energy suggests a ratio of 1 part TiO2 powder to 10 parts ethanol. This mix makes sure the TiO2 spreads well in the ethanol. It leads to a smooth coat on the glass, helping your solar cell work better.

Coating and Cooking the Titanium Dioxide Electrode

The first step is making the photovoltaic cell. You must put many thin layers of titanium dioxide (TiO2) on a glass slide. This builds the electrode that catches sunlight and turns it into power. You use a dropper or pipette to carefully drop the TiO2 on the glass.

Applying Multiple Titanium Dioxide Layers

After adding each layer, remove the extra TiO2 with a clean, dry tissue. This leaves just a thin TiO2 film. Do this step 10 times to get 10 layers of TiO2. The many layers make a strong and even coating that boosts the solar cell’s power.

Heating the Solar Cell to Remove Solvents

Heat the glass slide after adding all 10 layers. This burns off any leftover solvents and hardens the electrode. Put the slide in a clear, heatproof container on a hotplate. Heat it for 10 to 20 minutes. This gets rid of any ethanol or more and makes a firm TiO2 coating on the glass.

Staining the Cell with Berry Anthocyanins

The next step involves staining the titanium dioxide electrode with berry anthocyanins. These are natural pigments found in berries like blackberries and raspberries. They are good at capturing visible light. By soaking the TiO2 electrode in a berry dye solution, the cell can absorb more solar spectrum.

To make the berry dye, crush fresh blackberries or raspberries. Mix the juices with some water. Then, soak the titanium dioxide-coated electrode in this dye for about 30 minutes. This will make the electrode brightly colored and ready to boost the solar cell’s performance.

Using these eco-friendly materials is a great step towards building a solar cell. It can create clean and renewable energy. This is perfect for your home or a DIY solar panel project. Fenice Energy supports such green energy experiments for those interested in sustainable power and STEM.

Creating the Counter Electrode with Graphite

You’ll use conductive glass coated with graphite for your solar cell’s counter electrode. After rubbing a graphite pencil on the glass, a layer of carbon forms. This layer acts as a catalyst in the solar cell’s reactions. You’ll pair this carbon-coated glass with an electrode stained with titanium dioxide. This partnership completes the solar cell, letting you use renewable energy in a DIY way.

The graphite on the counter electrode is essential for the solar cell to work. It acts as a catalyst, making the reactions that produce electricity happen. This carbon layer improves how well the cell works by helping electrons move better between parts of the cell.

Adding the graphite counter electrode to your solar cell completes it and teaches you about solar technology. You get to build a working solar device and learn how solar power works. This project is a fun way to learn about renewable energy and the science of making electricity from the sun.

First, add an iodide-based electrolyte solution to one electrode. This solution is key for the cell to work well and produce electricity.

Assembling the Solar Cell Components

Now, carefully put another electrode on top. Make sure to offset them a bit. The setup is to make electrical connections easier later.

Clip the two pieces together. Your homemade solar cell is now complete and ready to check.

Adding the Electrolyte Solution

When the cell gets sunlight, it starts making a small electrical current. You can measure this using a multimeter.

The electrolyte solution helps with this by making sure the right reactions happen. Now, your DIY solar cell is set for testing and fun experiments.
